Electrolytic Capacitors: Comprehensive Overview, Teardown, and Experiments

Thanks to Nippon Chemi-con for sponsoring this video!

Through experiments, I compared different types of electrolytic capacitors such as solid and hybrid.

Very nice collaboration and informative video! It was great to have the EC differences spelled out.

[leegranite]

Hello from Canada. I like how you present your content and the English translation makes me keep coming back as I continue to learn. Keep up the clean, clear, and greatly informative videos. You’re doing great!

[WallaceRoseVincent]

Thanks Chemi-Con for supporting Denki Otaku, making Japan great again one capacitor at a time!

[GIGEO]

Excellent video! Very well put together information, thank you.

[jeromewhelan]

What an amazingly educational video. I have been in in the electronics business for 60 years, and this is one of the most clear and useful explanations I have seen on electrolytic capacitor technology and characteristics.

[Yreq]

I'm so impressed with this video. You managed to explain simple way what is the difference between electrolytic and solid caps. Domo arigato
BTW Chemi-con was always my favorite brand of caps

[gabotron]

Very clear explanations! I'm loving your videos Ichiken sensei

[PremiereHell]

That's why they always add an extra capacitor, That you think is not necessary but it is because it's preventing the other one from falling apart, Thank you for this well explained explanation. I was always curious about this.

[williammanganaro]

Excellent explanations ! I was amazed at the results of freezing the electrolytic capacitor and demonstrating its discharge curve. It made total sense to me when you did this. It was something I have never though of before. Makes you wonder if any "antifreeze" types of electrolytes have been researched. Probably so.

[techadmirer]

I had about 7 hours of research in capacitors in a general category and this video has taught me some useful information i didn't know of yet, Thank you for the video it's a much more entertaining way to learn instead of reading so i as well as some others with this same opinion have learned some of this information that otherwise likely wouldn't have been learned when avoiding forums, documents, catalogues, etc.

[tomjones]

Fascinating and informative. I didn't expect much at first, but as I got deeper into the video, the subject began to open up for me.

[buddyhoover]

The best explantion of electrolytics that I have seen. Keep up the good work.

[KF-bjce]

Very informative, presented so even a novice can understand it. Thanks so much.

[ELECTROxigeno.]

Nippon chemicon it's one of The Best caps Ever, tks for The great vídeo, 🎩

[Manf-ftzk]

Thank you very much for the very instructive video. I should learn more about the technology inside electrolytic capacitors.
What caught my attention were the pliers at 4:29. When I worked in Japan at a company with enough budget a local college bought very cheap pliers and he said it was just a cheap occasion. They got rusty after just a short time and I asked him to let me try to polish them and give them a little oil. He said he could throw they away any time, they were just cheap. We agreed to make the experiment and they looked better afterwards and were kept.
Just a personal memory inside the very valuable lesson about maybe the best capacitors and their different types.

[tomsherwood]

I have been trusting Japanese quality brands of electrolytics for a long time. Japanese electronics made as far back as the 70's still have good capacitors in them and they don't seem to need replacement, even though some people habitually do so out of worry. The capacitors that I do fear are ones made in China, or Chinese made fake copies of Japanese capacitors.

[MapleKlister]

Excellent video! Very informative, and at times humorous. Well done!

[NeoGhk]

Great presentation. I've unsoldered many types of these caps from PC bords but didn't know the differences between them.
Now I have an idea.
SUBSCRIBED.

[joshjones]

Your really good teacher an your make it Interesting to watch an funny.... Great video 👍👍👍

[GiNodrog]

Brilliant video and introduction to different types, also never thought of esr in parallel. You live and learn .
